ORE-CONCENTRATOR.

SPECIFICATION forming part of Letters Patent N0.`523,774, dated July 31,1894) Application tiled June 27, 1893. Serial No. 478.981. (No model.)

To all whom it may concern.-

Be it known that 1, THOMAS C. MCCLEEEY, acitizen of the United States, residing at Exeter, in the county of Fillmore and State of Nebraska, have invented a new and useful Ore-Concentrator, of which the following is a specification. 1

This invention relates to ore concentrators; and it has for its object to provide a machine of this character, the table of which is constructed with special reference to thethon ough and complete separation and concentration of the heavy particles of 'ore from the lighter particles of sand and other foreignV matter, such ore together with the sand and other matter being the tailings from ordinary quartz mills.

To this end the main and primary object of the present invention is to provide certain improvements in ore concentrating tables whereby the concentration of the ore will be more efliciently andeconomically secured.

With these and other objects in view which will readily appear as the nature of the invention is better understood, the same con-4 sists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

In the accompanying drawingsz-Figure l is a perspective view of` an ore concentrator constructed in accordance with this invention. Fig. 2 is a central longitudinal sectional view of the same. Fig. 3 is a vertical transverse sectional view on the line :r-- ofl Fig. 2. Fig. 4 is an enlarged detail sectional view of a portion of the concentrating table. Fig. 5 is a detail sectional view of the adj ustable connection. of the upper ends ofthe hanger wires with theupper frame cross bars.

Referring to the accompanying drawings, A represents a suitably constructed* base frame from opposite ends or sides of which arise the opposite frame uprights or posts B, connected at their upperends by the opposite upper frame cross bars C, thus completing a strong frame Work for the several parts of the machine, and the intermediate frame uprights or posts, which may be designated as D,valso act in the capacity of stationary strikeposts provided at one side thereof with the cushion buffers E,y thefunction of Which will presently appear.

Suspended within the frame work by the hanging or suspending Wires F, is the inclined concentrating table G. The hanging or suspending wires F, which loosely suspendv the concentrating table G, in an inclined position, are suitably attachedat their lower ends as at H, to the four corners of the table and have attached to their upper ends thethreaded adjusting stems l, projecting through perforations in the upper 'cross bars C, o f the frame, and engaged at their extremities above said cross bars by the adjusting nutsl J, which providemeans for adjusting the inclination E, of the Astrike posts intermittently, in order Y to provide for the dischargey of the concentrates on the table therefrom in the manner to be presently described, and this lateral movement of the concentrating table is Veffected by means of the oppositely locatedan'd oppositely moving pitmen K. The pitmen K, are pivotally connected at one end as at k, to the higher and lower ends of the concentrating table, respectively, and near the discharge side thereof, and are' attached at their other ends to the crank wheels L, at both extremities of the'longitudinally arranged drive .shaft M. The longitudinally arranged drive .shaft M is mounted in suitable bearings m,

at one side of the frame and carries a balance Wheel m', and a belt pulley 'm2, over which passes a suitable drive belt forcommunicating motion to the ore concentrating table. l

Referring more particularly to the con-y struction of the laterally vibrating and jarring concentrating table, the same comprises the opposite side pieces N, connected by the' imperforate bottom O. The imperforate bottom O, of the concentrating table leads from the upper receiving board P, to the lower tail or discharge chute p, and said bottom O, is

ICO

provided with a regular series of transverse oval depressions Q, forming an alternate se ries of oval ridges, which combine with the depressions to form a waving concentrating surface over which the water and tailings run in regular waves, conforming to the configuration of the table bottom, and thereby securing a thorough concentration of the ore out of the tailings. In the bottom of the oval depressions Q; are formed the stinken semi,- circular discharge grooves S. The discharge grooves S, formed in the oval depressions Q, also extend transversely of the concentrating table and lead at one end into the side discharge openings T, formed in one of the side pieces N, of the concentrating table,` and through which are designed to pass the concentrates which fall into the receiving and grading trough U. The trough U, is mounted on the base frame A, and is disposed slightly under the discharging side of the concentrating table, and may be provided withone or more partitions u, according to the number of grades into which it isl desired to collect the concentrates. An overiiow pipe V, is connected with one end of the trough U to carryo the overflow of watertherefrom.

Suitably arranged over the higher receiving end of the concentrating table and discharging onto the receiving board P, at the upper end thereof, is the feed spout or trough W, through which the ore and water pass from any quartz mill to which the concentrator may be attached, and alongside of the feed spout or trough is arranged an auxiliary or supplemental water supply pipe w, provided with a series of valved discharge nozzles w', which provide means for regulating the necessary amount of water supply, in order to thoroughly wash away all the sand and waste, thereby leaving the concentrates perfectly clean in the semi-circular discharge grooves S, of the table.

The concentrating table G, is held steady in its lateral vibrations by means of the transverse guide rod X. The transverse guide rod X, is secured to the bottom of the concentrating table at the higher end thereof and projects beyond the opposite sides of the table so as to work in rear of the vertical guide rollers Y. The vertical guide rollers Y, are mounted on oE-standing brackets Z, attached to the frame uprights-or posts at each side of the concentrating table. l

Now from the foregoing it is thought that the construction and operation of the herein described concentrator will be perfectly clear to those skilled in the art. In the first place, the specific construction of the bottom of the Atable provides for directing the tailings and water thereover in even waves,so that the heavier particles of ore will settle in the semicircular discharge grooves in the bottom of the oval depression, and will thus be thoroughly separated and concentrated from the sand and other matter, which are washed 0E at the lower end of the table by the running water. The constant side jarring of the table causes the concentrates to be jarred out of the grooves S, and through the side discharge openings T, from which the concentrates fall into the grading trough U, at one side of the table. The surplus water supply greatly aids the operation of cleaning the concentrates perfectly of the sand and other matter.

Slight modifications in the construction described might readily suggest themselves, and I will therefore have it understood that changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention, what 8 5 is claimed, and desired to be secured by Letters Patent, is-

In an ore concentrator, the combination of the frame having stationary upright strike posts, an 4inclined laterally swinging concentrating table suspended within the frame and having an imperforate bottom provided with transverse grooves, and side discharge openings perforating one of its sides and communicatingwith one end Yof said grooves, a suitably arranged guide to hold the table against longitudinal movement and means for intermittently moving the perforated `discharging side of the concentrating table against said strike posts, substantially as set forth.
